citizen of the. United States of America, re

siding at Fairchance, in the county of Fa- -5-' yette and xState of Pennsylvania, have in vented-certainznew and useful Improvements vin Combined Rail Chairs and-Joints, of

' which the following is a specification, reference being hadxtherein to the accompanying" drawing.

This invention relates to a combined rail chair and joint and has for its object to pro .vide a device of such class, in a manner as hereinafter set forth, for connecting the opposing ends of a pair of track rails together without the employment of nuts and bolts, atthe same time provide for the necessary contraction and expansion of the track rails, due to climatic influences.

Further-objects of the invention are to provide a' combined rail chair and joint which is comparatively simple in its construetion and arrangement, strong, durable,

readily set up and efficient in its use.

With the foregoing and other objects in view the invention consists of thenovel construction, combination and arrangement of parts as hereinafter more specifically de-'.

scribed and illustrated in the accompanying drawings wherein is shown an. embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope-of the claims hereunto appended. In the drawings wherein like reference characters denote corresponding parts throughout the several views :-Figure 1 is a side elevation of a. pair of track rails, broken away, showing the adaptation therewith of a combined rail chair and joint in accordance with this invention. Fig. 2 is an elevation, looking toward the other side of the track rails, showing the adaptation thereto of a combined rail chair and joint in accordance with this invention. Fig. 3

is a vertical sectional view on line XX,

; eferring to the track rails and each in- 2- denote a pair of I cludes a head 3, web 4. and base 5. One side of the head of each rail in proximity to each end, is cut away to form a vertical extending groove 6, the inner wall of whlch 1s flush with one side of the web 4. Each of the track rails has its web 4, in proximity to Specification of letters Patent.

eachend, provided with a pair of lateral 'extending pins 7, 8, positioned approximately centrally with respect to the top and bot- .tom of the web' 4. The-pins 7, 8, of one track rail are arranged in alinement with the p1ns'7, 8, of the'other track rail.

The reference character 9 denotes a chair plate, adapted to be mountedupon a tie, and formed with openings 10 for the passage of hold fast devices to secure the plate 9 from movement.

Formed integral with the upper face of the plate 9, at a point between its center and one end thereof, is'a transversely extending and vertically disposed arm 11 which is bowshaped in vertical section. 7

Formed integral with the upper face of the plate 9, at a point between its center and the other end thereof, is a transversely extending vertically disposed rib 12, which terminates in an inwardly extending base flange 13, the latter merging in a vertically disposed fish plate 14, which, when the chair plate 9 is in position, extends to a point in close proximity to the pins 7 8.

The reference character 15 denotes a rectangular member which constitutes the other fish plate and which is formed with openings 16 for the reception of the pins 7 The top edge of'the member 15, is formed with ,whieh is in abutting engagement with one side of the web 4, by a wedge 18, which is interposed between the arm 11 and the lower portion of the member 15. The wedge 18 is cut away as at 19 so that it will seat itself upon one side of the bases 5 of the track rails 1, 2.

To prevent longitudinal movement of the wedge 18, a vertically disposed pin 20 is employed, which extends down through one end of the wedge 18, and engages in one side of one of the bases 5 of the track rails.- The wedge 18 is termed a retaining member.

What I claim is I 1. A combined-rail chair and joint comprising a chair 'plate having formed in- I tegral with its upper face a transversely extending arm bow-shaped in vertical section, and further having connected to its upper face a fish plate provided with a base flange, a pair of track rails mounted upon said plate and over-lapped by said base flange and each provided With a pair of oppositely disposed pins arranged above the top of said fish plate, each of said track rails having its head, at one side, cut away in proxiinity to an end thereof, to form a groove, a fish plate positioned against said track rails and having openings for the reception of certain of said pins and further having lugs extending in said grooves and a retaining member interposed between said arm and the last mentioned fish plate.

2. A combined rail chair and joint comprising .a chair plate having formed integral with its upper face a transversely extending arm bow-shaped in vertical section, and further having connected to its upper face a fish plate provided with a base flange, a pair of track rails mounted upon said plate and overlapp id bysaid base flange and each provided with a pair of-onpositel disposed pins arranged above the top of said fish plate, each of said track rails having its head, at one side, cut away in proximity to an end thereof to form a groove, a fish plate positioned against said traik rails and having openings for the reception of certain of said pins and further having 7 lugs extending in said grooves and are taining member interposed between said arm and the last mentioned fish plate, and means engaging in one of the track rails and with. said retaining member to prevent longitudinal movement thereof.

In testimony whereof I afiix my signature in the presence of two Witnesses.
